By default "./configure " will proceed to run itself and collect all the system information. I am thinking of writing my own configure.ac to generate configure to split out the content of "--help" or shoowing a usage message when there is no argument provided. Following code in configure.ac doesn't exit out right away when I type in "./configure" MYARGS=2 if test $# ne $MYARGS then echo "Need one argument at least.\n" exit 0 fi Anyone know there is a similar configure.ac I can learn from ? -- T.J.
